The hub 25 isprovided with a locking bolt 44 which is adapted to bear against thebody 14.

In operation, it will be seen that a wheel with a tire to be worked uponis placed upon the supporting arms 16 and that the collar 23 is thenplaced over the body I4, the flange 24 resting upon the wheel 37.Thereupon the hub 25 is placed over the body 14 in such-manner astorestupon the upper end of thecollar 23 and the lock bolt 44 t e -,1 T L:$h P1 0 of t lever 29 is inserted intothe openi g 29 the do 2 a d the foot3l placed against the bead o f-the tire 38 and the l-ever ,i s;,thenpressed'downwardly, he b ca i p essure t e pl Po the ee to loosenthe same from the tire 31; This action may k p e e-thr i houtne entircumfee ence of the tire due to the fact that the hub 25 is revolubleupon the body [4. While it necessaryto loosenthe bplt' 44 each time thehub 25 is moved toa new, position, it is usually only necessary to causebut one downwardmovernent of the foot 3 i tobreak the tire bead loosefrom the rim.

The bead-engaginghook 2| of the lever is then inserted between the headof the tire and the wheel in the manner shown in Figure 6 and the levermoved ,ini the direction of the arrow in that figure or toward thecenter of the wheel. "Ihenotches 22 may then be. engaged with thenotches]?! and,isi nce the support l 8.is revoluble within the body-l4,the lever and its bead-engagingendi'niay .therib moved throughoutthe'entirciicii mfrenceofthe wheel, thereby to' loosen meb'eau rrqmmwheel..

The rod 34 will, of course, be inserted into one or the other of thehousings 32 "or 40, depending upon the type of 'wheel and the spring 33will 4 act as shock-absorbers, thus allowing for greater wear and lessnoise in this particular operation.

In the case of certain now obsolescent wheels, it is necessary tosubstitute the collar 42 for the collar 23 in order that the arms 43 maybe enabled to secure the wheel in such case.

While but one form of the invention has been shown and describedhereirnit will be readily apparent to those skilled in' the'art thatmany minor modifications may be made without departing from the spiritof the invention or the scope of they appended claims.

What is claimed is:

1.A tire changer comprising a hollow cylindrical body, supporting legsfor said body, wheel and tire supporting arms afiixed to said body, a

1 bolt transversely mounted in said body, a cylindricalsupport'revolubly mounted in the body upon said bolt and having anotched upper end, a tire-removing lever having a series of serrationsalong one side adapted to lock with said notch, and means for locking 2.wheel against rotary movement upon said wheel and tire supporting arms,said last mentioned means comprising a vertically extending rod housinghavingan open upper end adapted to receive a rod extended'through one-ofthe conventional lug bolt openings of a tire.

2. A tire changer comprising a hollow cylindrical body, supporting legsfor said body, wheel and tire supporting arms afiixed to said body, abolt transversely mounted in said body, a cylindrical support revolublymounted in the body upon said bolt and having a notched upper end,

a tire-removinglever having a series or serrations along one sideadapted to lock withsaid notch, and means f or,- locking a wheel againstrotary movement upon said wheel and tire supporting arms said lastmentioned means comprising vertically extending rod housings mounted atdiiferent radial distances-fromthe housing and each having; an openupper end adapted to receive a rod extended through one of theconventional lug bolt openings of a tire and having a spring buffer forthe rod in the lower end thereof. f I V v u ROGER M, PATTERSON.
